Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology
Geostandards and Geoanalytical Research, EarlyView.Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

A New Approach to Transforming Airborne Electromagnetic Data into Models of Sediment Type
Groundwater, EarlyView.A new methodology provides the relationship needed to transform electrical resistivity measurements from airborne electromagnetic surveys to sediment type. By accounting for the physics of the measurement and the quality of the driller's logs used in developing the transform, the method improves the accuracy of derived sediment type models.

Insect Conservation and Diversity, EarlyView.Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

Two‐dimensional guillotine cutting problem for large objects with non‐rectangular shapes
International Transactions in Operational Research, EarlyView.Abstract In this paper, we address the two‐dimensional single large object placement problem with guillotine cutting constraints, focusing on non‐rectangular shapes. We consider objects with circular or convex polygonal geometries and study a variant that includes defective regions from which no items can be extracted. Rectangular items are cut using a
